Troubleshooting your hydraulic problem with out testing some functionality of components is next to impossible but I will give you some ideas to check. First, since your unit is a 2008, if you haven't changed the fluid do it. The fluid is a DOT III ATF fluid at any auto store. As the fluid is open to the atmosphere via the chambers fill port it is hydrostatic (absorbs water) which can cause compression in the fluid and pump low pressure. Second there is probably debris in the fluid which can keep valves open allowing leak back. So when it is drained out take a flashlight and look for debris in the bottom. When you've finished refilling and cleaning the debris out, cycle the slides three or four times to remove any air that may be in the system.
DOT 3 is brake fluid not ATF. OP do not fill your system with brake fluid, check with manufacturer on what to use.
Correct some use hydraulic fluid ,some use ATF. My manual said ATF, but it came from the factory with hydraulic fluid, was pretty obvious it was not ATF .
